We found that before licking, both D1 and D2 cells transiently increased their activity, which peaked just after licking onset. In both D1 and D2 cells, the peak was more pronounced in response to milkshake than water. This may reflect hedonic processes (Fig.1b–d) rather than nutrient ...
There was also no evidence that the rats were simply disorganized or disengaged during omissions after D1R administration; analysis of the patterns of responding in a subset of animals showed that they performed many of the same action sequence components on these trials as observed on correctly ...

C. “D1–D2 Receptor Synergy” In addition to the ability of either D1 or D2 receptors to independently regulate gene expression in the striatum, combined activation of D1 and D2 receptors evokes quantitatively greater and qualitatively different patterns of gene expression in the striatum – ...
The nucleus accumbens (NAc), a major structure of the ventral striatum, is traditionally involved in behaviors that are critically dependent on heightened arousal, such as motivation, reward, and movement.6, 7, 8, 9 Loss of consciousness (LOC) and recovery of consciousness (ROC) from GA are...
Our results highlight a role for dopamine D1 receptors, probably within the basal ganglia, in the production of sequential super-stereotypy of complex behavioral patterns. Synapse 37:205–215, 2000. © 2000 Wiley-Liss, Inc.doi:10.1002/1098-2396(20000901)37:3<205::aid-syn4>3.0.co;2-a...
Cannabinoid CB1 receptors are densely expressed on striatal projection neurons expressing dopamine D1 or D2 receptors. However, the specific neuronal distribution of CB1 receptors within the striatum is not known. Previous research has established that t

He animated small-scale models by photographing them one frame at a time, making slight adjustments to their positions between each shot to give the impression of movement. This process required patience and precision. One of his most famous scenes is in the 1963 filmJason and the Argonauts. ...
